A Correct answer
Explanation

Rayon is chemically identical to cotton because both are composed of cellulose. Rayon is produced by regenerating natural cellulose from wood pulp, so its chemical structure is the same as cotton's cellulose. Nylon (polyamide), silk (protein), and polyester have completely different chemical compositions.
